That “hairy” outline isn’t a style. It’s a control issue. When you build a contour with lots of short, staggered strokes, the edge gets fuzzy. The form loses clarity. It starts to vibrate instead of read as a solid shape. A clean contour usually comes from fewer, more confident lines. One intentional stroke that follows the form will always read better than ten hesitant ones. Control fixes this. It lets you commit to the path of the line, keep the edge consistent, and decide where to vary weight
